Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climatedamaging carbon dioxide. This book explores how efficiency is measured and reported at coalfired power plants.

WhatsApp: +86 18203695377Ammonia (NH3), as a derivative of hydrogen and energy carrier, is regarded as a lowcarbon fuel provided that it is produced from a renewable source or a carbon abated process of fossil fuel. Cofiring ammonia with coal is a promising option for pulverized coalfired power plants to reduce CO2 emission. Applying the cofiring in an existing pulverized coalfired boiler can achieve satisfying ...
